This is normal.
The purpose of Xinghe is to enable mechas to have combat capabilities in space, and not just in space. Whether it's Ji Xinghe, Star Moon, or Shen Mu, as well as the personnel from the Federation Science Academy and other related institutions involved in the design and manufacture of Xinghe, they all believe that when the Empire potentially uses that spacecraft from the Third Civilization to directly attack Azure Star, the battlefield is highly likely to be within Azure Star's atmospheric environment.
Therefore, in terms of design goals, Xinghe has air-space integrated combat capabilities, and after being built, Xinghe did not disappoint.
Unfortunately, due to various reasons, Xinghe did not play the critical role as expected during its design and manufacture; it merely carried Ji Xinghe to Imperial Star, endured several rounds of concentrated fire from the Empire, and helped Ji Xinghe break down a mere thirty-seven Imperial air-spacecraft.
